This secondary high-limit control provides an additional layer of overheat protection beyond the primary limit, interrupting the burner circuit if temperatures in its monitored zone exceed the safe threshold. The color coding corresponds to a specific trip temperature, so matching the OEM part is critical.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Auxiliary (secondary) bimetal high-limit switch\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (temperature-specific)\u003c\/li\u003e\n\u003cli\u003eFunction: Supplemental overheat safety cutoff\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bracket \/ snap-disc, spade terminals\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ACEC800603BXAA and compatible gas furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe light blue OEM 0130F00038 is factory-calibrated to Goodman's exact trip point.
